Outline


Introduction

  • 1965 ; Wilson
    • Wilson thought the lithosphere was broken into pieces
    • pieces called plates.
  • the plates fit closely together.

Plate Motion

  • Transform boundary
  • Divergent boundary
  • Convergent boundary

The Continent's Slow Dance

  • plates move at amazingly slow rates.
